RUBBING-POST.

Specification of Letters Patent.

Patented May 15, 1217.

Application filed September 8, 1914. Serial No. 860,638.

To all whom it may concern Be it known that I, REUBIN H. BLOOMER, a citizen of the United States, and a resident of Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented certain new and useful Improvements in Rubbing-Posts, of which the following is a specification, reference being had to the accompanying drawings.

This invention has relation to certain new and useful improvements in rubbing posts.

The object of my invention is to provide a rubbing post arranged to be given a firm support in a hog pen or run, and includes a plurality of vertically reciprocating rub bars, each of which when actuated unseats a valve, permitting a liquid insecticide or oil to flow down the bars and spread over the animal actuating the rubbing bar.

Another object is to provide a rubbing post so constructed as to accommodate hogs of all sizes, the arrangement being such that there will be no unseating of the valves should a hog go to sleep lying against a rubbing bar.

A further object is to provide a rubbing post including a vertically reciprocating rub bar provided with a plurality of diagonally extending drain channels, each of which communicates wlth an extending rib pro jecting beyond the sides and outer edge of the bar.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and finally pointed out in the appended claims, it being further understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings forming a part of this specification, and in which like numerals of reference indicate similar parts in the several views:

Figure 1, shows an elevational view of a rubbing post embodying my invention.

Fig. 2, shows an enlarged sectional view disclosing a fragmentary portion of the upper end of the post. i

Fig. 8, is a detail of one of the ribs, showing a fragmentary portion of a rub bar.

In my present invention I provide a rubbing post which is preferably secured to a platform P, sunk so that the top of the platform comes level with the surrounding ground.

The post proper comprises a standard cruciform in cross section and including four webs 1, which end in the apertured securing base 2, through which pass suitable bolts 3. As shown at a, in Fig. 1, the upper portion of each web is slightly less in width than the lower portion. This is done so that the rear edges of the reciprocating rub bars will not contact with the webs.

At its upper end the standard is provided with the reservoir 4t, having a centrally disposed settling chamber 5, within which is collected the sediment and impurities within the insecticide or oil.

Within the bottom 6, of the reservoir are located a plurality of valve seats 8, having the enlarged drain openings 9, these openings passing through the bosses 7, as clearly shown in Fig. 2.

Held to each valve seat 8, is a valve 10, having an extending stem 11 carrying a nut 12, a spring 13, being interposed between each nut 12, and a boss 7, to insure the normal firm seating of each valve.

The stems 11, are of a diameter less than the diameter of the drain openings 9, to insure a free flow of the liquid through the valve openings.

As clearly shown extending parallel with the bottom 6, of the reservoir 4:, are four similar yokes 14:, these yokes having the apertures 7), the yokes preferably forming an integral part of the standard.

ured near the lower portion of the standard and immediately below the yokes upon opposite sides of the webs 1, are the links 15, these links being used in sets of twos, and pivotally held to the standard by means of the pivot pin 17 As shown in Fig. 1, the links 15, end in a straight portion 16, arranged to stop in one position against an adjacent web 1, in the manner insuring these links extending outward in a horizontal plane.

Each set of links 15, carries a pin 18, to each of which is pivotally secured the lower end of a rub bar A, the rub bars being capable of being vertically reciprocated and having their upper ends slidably held within the yoke openings 1).

As shown in Fig. 2, each rub bar A, ends in a guide neck 19, and these guide necks are held. within the yoke openings 6, immediately below the valve stems 11, so that an upward movement of bar A, results in the adjacent valve being unseated.

These links 15, limit the downward 1novement of the bars A, the upward movement being limited in that the lower end of the bars A, come in contact with the webs 1, near their lower ends.

At its upper end each bar A, has a circumscribing obliquely held collar 20, with a rounded under-face 0. These collars prevent any oil or insecticide sliding down the rear or inner edge 00, of the rub bars, and insure the material draining downwardly to drop upon the first rib and then successively over and through the adjacent ribs 24-, and drain channels 22.

It is of course understood that owing to the curved under-face c, of the collar 20, the insecticide or oil covers and glides down both sides or faces of the bars, as well as the outer edge Q), of each bar.

As shown the collar 20, and the ribs 2%, extend in parallel spaced relation, the ribs 24, which also have a curved underface forming a continuation of a channel 22.

The channels 22, have the bottoms 23, at right angles to the faces of the bars, A, as shown in Fig. 8, and extend more than half way across the bar. Forming a continuation with the bottoms 23, are the ribs 24, the upper faces of which lie in a plane coincident with the face of the bottoms 23. The ribs project beyond the forward edge e, of the bars, as well as beyond the sides of the bars and are gradually reduced in width rearwardly toward the channels. This insures the insecticide or oil draining toward the outer edge of each rib which have rounded underfaces increasing the oil bearing surface of each rib, while preventing any liquid dropping off of the ribs as would be tee case where the ribs end in sharp corners or edges.

The operation of the device is very simple. The odor of the insecticide or oil attracts the 110g and they soon become accustomed to scratch themselves against the rub bars. A mere lateral pressure or a pressure in a horizontal plane against one of the bars will not unseat a valve and forms a special feature of my invention. hen a hog rubs itself there is exerted a lateral pressure, as well as an upward pressure, and it is the upward pressure of the animal that results in the bars A, being carried upward to unseat the valves. Under these conditions should a hog lie against one of the bars A, the valves will not be unseated. The use of these rubbing posts is found beneficial in that scurvy, hog lice, and skin diseases are prevented or cured.

The rub bars A, are of such a length that they come so low that even a small hog, well as a large hog may use the rubbing post constructed according to my invention, and

little pigs can operate the device as readily as a large hog. V

Tn referring to Figs. 1 and 2, it will be noticed that there is a slight play between the upper end of the necks 19, and the lower ends of the valve stems 11. In lying against the rubbing post a hog might slightly raise a rub bar A, but this upward movement would not be sufficient to unseat a valve.

A rubbing post embodying my invention is simple inexpensive in construction, and both durable and eificient in operation, and the rub bars of the post may be positively operated with ease, accuracy and despatch, to insure a beneficial distribution of the insecticide or oil.

Having thus described my said invention, what I claim as new and desire to secure by Letters Patent is:
